Cluster headache attacks in a woman previously struck by lightning: pathophysiology of the latent period.

BACKGROUND Cases of patients who developed cluster headache-like symptoms after different putative causes have been reported, indicating a direct relationship between brain lesion and this particular type of headache. Long term, delayed, neurological sequelae after lightning have also been described. CASE REPORT We describe the case of a woman who, at the age of 10, was struck by lightning. Six years later she developed cluster headache-like attacks. CONCLUSION We hypothesize that a relationship between the lightning and the cluster headache-like episodes observed in our patient. This case study may have helped throw some light into the still unknown pathophysiology of this particular type of primary headache.
